Energy-consuming fabricated hollow shear wall with embedded columns and construction method
The invention discloses an energy-consuming fabricated hollow shear wall with embedded columns and a construction method. The energy-consuming fabricated hollow shear wall comprises a prefabricated hollow shear wall body with the embedded columns on the upper portion, a prefabricated hollow shear wall body with the embedded columns on the lower portion, disc spring devices, brackets and laminated slabs. The upper hollow shear wall body with the embedded columns and the lower hollow shear wall body with the embedded columns are rapidly centered and positioned through the upper U-shaped steel plate and the lower U-shaped steel plate, the upper U-shaped steel plate and the lower U-shaped steel plate provide friction energy consumption, the disc spring device has high anti-pressure capacity and can restore to the state before deformation after unloading, restoring force is provided for the wall body, and the safety of the wall body is improved. The post-earthquake residual deformation of the structure is reduced; the bracket is arranged to be connected with the laminated slab, parallel pouring is adopted for post-pouring, ultra-high performance concrete is poured on the upper portion of the bracket, common concrete is poured on the upper portion of the laminated slab, and the ultra-high performance concrete and the common concrete have good shear resistance and tensile property. The structure node is clear in force transmission and reasonable in stress, the post-earthquake damage and residual deformation of the structure can be reduced, and the later repair cost is low.
本发明公开了一种耗能带暗柱装配式空心剪力墙及施工方法，包括预制上部带暗柱空心剪力墙、预制下部带暗柱空心剪力墙、碟簧装置、牛腿和叠合板；上部带暗柱空心剪力墙与下部带暗柱空心剪力墙通过上部U型钢板和下部U型钢板实现快速对中定位，上部U型钢板和下部U型钢板提供摩擦耗能，碟簧装置具有较高的抗压能力，卸载后能恢复到变形前的状态，为墙体提供恢复力，减小结构的震后残余变形；设置牛腿与叠合板连接，后浇采用平行浇筑，牛腿上部浇筑超高性能混凝土，叠合板上部浇筑普通混凝土，超高性能混凝土和普通混凝土具有良好的抗剪性能和抗拉性能。本发明结构节点传力明确、受力合理、能减小结构震后损伤和残余变形、后期修复成本低。
